The CH7304 is a Display Controller device, which accepts a graphics data stream over one 12-bit wide variable voltage (1.1V to 3.3V) port. The data stream outputs through an LVDS transmitter to an LCD panel. A maximum of 100M pixels per second can be output through a single LVDS link.

The LVDS transmitter supports 24-bit panels; it also includes a programmable dither function for support of 18-bit panels. Data is encoded into commonly used formats, including those detailed in the OpenLDI and the SPWG specification. Serialized data output on four differential channels.
